dark mode input value not visible when focus out.

I'm using nebular ngx-admin and i'm facing some undesired behavior with smart-table cells on dark mode. In fact, after writing on some input, and when focusing out, the input value gets white, so it's invisible. To see the value again I must focus on the input. That's kinda shitty. Notice that I didn't make any change to the original source yet. It seems to be the default behavior (you can see it [here](https://www.akveo.com/ngx-admin/pages/tables/smart-table) )

Is there any way to customize this behavior ? Thanks.
